Directly chat with user upload file without embedding.

[skybearlove]

Hi,
Which chain I can use to directly let user to chat with user upload files without embedding files to vector store? Just like we do in Chatgpt where we copy text as well as our question to Chatgpt, and get answer.

I image that file loader can load file content as text, and use that content and our question as input to chat chain and get answer. Do we have nodes that can complete this feature?

Thanks
